std::locale
Member types locale::id locale::facet Member functions locale::locale locale::~locale locale::operator= locale::combine locale::name locale::operator== locale::operator!= locale::operator() Static member functions locale::global locale::classic

Defined in header <locale>
id();	(1)
id(const id&) = delete;	(2)

1) default constructor: creates an object of type std::locale::id with implementation-specific content.

2) copy constructor is deleted; std::locale::id is not copyable.

[edit] Notes

Because locales and facets must be available for the IO stream objects with static storage duration, such as std::cout, typical implementations let implicit default constructor zero-initialize the contents of std::locale::id during static initialization (before constructors run for static objects), and when a facet is added to any locale for the first time, the locale completes initialization of the facet's id.
